RRUK Scanner Linker 2.0 - Automatic Frequency Lookups

Scanner Linker 2 introduces a host of new features including logging and audio recording. The main window retains its familiar compact look but additionally now shows Colour Code, RAN, TGID, CTCSS and DCS (scanner dependant).

DMR Beacon Skip

If using a Uniden HP type Scanner (SDS100E/200E, UBC3600XLT, BCD436HP/536HP) a DMR Beacon Skip checkbox will be displayed in the main window. This analyses the current channel data and will resume searching or scanning if the analysis has concluded the scanner is stuck on a beaconing DMR signal or a Tier 3 control channel. For this option to work optimally you also need to connect the scanner audio to your mic or line input.

Scan Timeout

A global scan timeout can be set in the main window menu (dependant upon scanner used). This will force the scanner to resume scanning after the fixed time selected, ideal for unanttended logging and recording.

Logging and Audio Recording

Selecting "Scanner Log" from the menu will open the new log window. If you have previous log entries you will be prompted to restore the old log, this is useful if you wish to continue logging over multiple sessions.

Local Log Window

To use the recording feature, you need to connect your scanner to a microphone or line input on your PC, normally this will be via a 3.5mm audio cable from the earphone socket to the sound card.

At the bottom left of the window you will see the audio level meter and gate control, the audio level must be greater than the gate to record. Below this there is an "Open Recordings" button, this opens the folder where the audio recordings are stored. Audio recordings are meta tagged with Date/Time, Frequency, User, Colour Code, TGID, CTCSS, DCS (scanner dependant) so you can playback in the player of your choice and check exactly what was recorded.

Recordings can also be played directly from the log grid by double clicking the row (double click again to stop playback).

There are 4 checkboxes at the bottom of the window.

• Auto Add to 'local_hits.log' - If checked hits are also stored to a file called local_hits.log.
• Allow Duplicates - If checked each hit is recorded on a new line. (Recommended)
• Only Log If Audio - If checked entries will only be logged if audio was detected, scanner audio must be connected. (Recommended)
• Listen - If checked the audio input the scanner is connected to will also be routed to the PC sound output so you can listen. (Recommended)

The log window itself contains 10 columns, the first column will have a + symbol which can be clicked to show alternative matches found for the logged frequency. If the triangle (play) symbol is present in this column then there is an audio recording, double click to play or stop playback.

The code column will display the code from the database (if available). If you wish us to add codes for your area, eg colour codes, RANs, CTCSS or DCS then please email them in.

The Live and TGID columns will read the Live Colour Code and TGID from the scanner, this is scanner dependant. If the CC, RAN, CTCSS or DCS is in the database the system will try to match the live and database codes. To work optimally please submit codes for your area. If there is no code in the database, logs will be sorted by closest signal to your postcode.

To the bottom right of the log there are 4 buttons. Clear Selected and Clear All will clear selected or all entries from the local log.

Exporting

The Export ALL and Export Selected to Master will export entries to the Master Log, which will open, and then can be exported to a csv file.

The recommended operation is to click the "+" symbol (where there is more than one option), select the matching entry then export that to your Master Log for saving.

Export All exports all parent level matches where the nearest signal was selected (or code matched) but may not be the actual correct match, we recommend exporting the selection individually.

Live Mil and Mil Logging

Live Mil and logginf of Live Mil remains the same as previous.

When you stop on an active Military Airband frequency simply press the green "Log Active" button to add the frequency to our Live Mil system.

Live Mil frequencies can be viewed on the web at the Live Mil page or directly within the Linker App via the Live Mil log window.

How Scanner Linker Works

Scanner linker uses your RRUK account and postcode to download a database tailored to your local area, it downloads all frequencies within a 50 mile radius of your postcode as well as all Airport, Airfield, Military Airband and Nationwide frequencies. Scanner linker then connects directly to your scanner and gets the frequency you are tuned to, it then does a superfast lookup against the database it has automatically downloaded and displays the nearest 3 users of that frequency. Each time you start Linker it updates the database so you're always up to date.

To use scanner linker you need to connect your scanner to your Windows PC or Laptop, for many scanners this is simply a USB cable, for some of the older models such as the AOR AR8600 they require a USB to RS232 adapter cable. Scanner linker connects directly to the COM port your scanner is attached to, it reads the frequency you are tuned to and displays the 3 nearest matches including distance from you and the direction in degrees. For recording and for some features, an audio connection between the scanner and your PC is required.

Scanner linker doesn't require any third party software to talk to your scanner, you simply run our app and it does all the work.

Scanner Linker with SDRs - SDRUno / SDRSharp

Scanner linker can operate with your SDR using SDRUno or SDRSharp software, to make things simple Scanner Linker uses its own Omnirig profile to talk to SDRUno and SDR Sharp, Omnirig is a free utility for radio and scanner control, SDRUno has Omnirig functionality built directly into it and SDRSharp has a plugin module.

An active RRUK subscription is required to run scanner linker and your PC must be connected to the internet.
